Definitions

  • the present invention relates to an adjustable housing assembly for use on a slide gate or sliding closure unit for controlling the discharge of molten metal from a metallurgical vessel. More particularly the present invention relates to such an adjustable housing assembly of the type including a housing member to be mounted on the metallurgical vessel adjacent a molten metal outlet thereof, and a cover member mounted on the housing member by means of joints to enable the cover member to pivot with respect to the housing member and to be removable therefrom.
  • Sliding closure units normally are mounted on the bottoms of metallurgical vessels.
  • the mounting of the sliding closure units causes considerable problems.
  • it is difficult to find a favorable and optimal mounting location for the sliding closure unit and its drive unit since often there is not sufficient space available for the necessary pivoting of a cover member of the housing assembly of the sliding closure unit to enable rapid and thorough maintenance thereof.
  • West German Patent DE-PS 29 41 027 discloses a rotary sliding closure unit including a housing assembly having a cover member pivoted upwardly selectively from two opposite sides of a housing member by releasing one of two opposed pairs of hinge pins.
  • a housing assembly including a housing member to be mounted on a metallurgical vessel adjacent an outlet thereof, and a cover member mounted on the housing member by means of joints to enable the cover member to pivot with respect to the housing member and to be removable therefrom.
  • the joints include joint bases on at least four sides of each of the housing and cover members including, for each of the housing and cover members, first and second oppositely spaced sides with the joint bases thereof defining parallel first and second joint axes, respectively, and third and fourth oppositely spaced sides with the joint bases thereof defining parallel third and fourth axes, respectively.
  • the joint bases of the respective side of the housing member face joint bases of the respective side of the housing member.
  • the cover member is selectively mountable along more than one side of the housing member, such that the cover member may be pivoted in different directions to be accommodated to space requirements at a particular installation. Specifically, it is possible to pivot the cover member in a horizontal or lateral direction, as is optimum for the surrounding conditions at a given installation location.
  • the joint bases on at least the first, second and third sides of each of the housing and cover members are identical, and preferably such joint bases comprise respective pairs of projections.
  • the attachment means is in the form of strap members selectively hinged to the joint bases of the first sides of the housing and cover members or to the joint bases of the second sides of the housing and cover members.
  • the cover member may be mounted in a manner to be selectively pivotable with respect to the housing member about the first axes or the second axes.
  • the attaching means further includes locking levers selectively connectable to the joint bases of the second sides of the housing and cover members or to the joint bases of the first sides of the housing and cover members, such that a cover member is locked or released with respect to the housing member along the second sides or along the first sides thereof.
  • the attachment means when the joints are arranged along the third and fourth sides, rather than along the first and second sides, the attachment means includes strap members selectively hinged to the joint bases of the third sides of the housing and cover members, such that the cover member is pivotable with respect to the housing member about the third axes, and a latch member is positioned substantially within the housing and cover members and cooperates with the joint bases of the fourth sides thereof, thereby to lock or release the cover member with respect to the housing member along the fourth sides.
  • the joint bases on the fourth sides of each of the housing and cover members comprise respective pairs of projections identical to the projections on the third sides thereof.
  • the strap members rather than being selectively hinged on the joint bases of the first or second sides of the housing and cover members, in this arrangement also or alternatively may be hinged to the joint bases of the third sides or the fourth sides of the cover and housing members.
  • the cover member is selectively pivotable with respect to the housing member about the third axes or about the fourth axes.
  • the locking levers selectively are connectable to the joint bases of the fourth sides of the housing and cover members or to the joint bases of the third sides of the housing and cover members. Thereby, the cover member is locked or released with respect to the housing member along the fourth sides or the third sides thereof.
  • a centering ring to be fixed to the metallurgical vessel coaxially of the molten metal outlet axis, and the housing member is mounted on the centering ring at a plurality of relative positions with respect thereto about the outlet axis.
  • the housing member is connected to the centering ring by means of at least three bolts which are threaded into the centering ring at respective positions equally circumferentially spaced about the outlet axis.
  • three such bolts are provided, then they are threaded into the centering ring at positions spaced circumferentially by 120° with respect to each other.
  • the number of bolts however may be increased as desired, thereby increasing the number of relative positions of the housing assembly with respect to the metallurgical vessel, and thereby increasing the*4 number of directions at which the cover member may be pivoted.
  • the sliding closure unit is of the rectilinearly movable type, normally with a rectangular configuration, then preferably there are provided four attachment bolts spaced circumferentially from each other by 90°.
  • FIG. 1 is a view, partially in longitudinal section and partially in elevation, of a sliding closure unit mounted adjacent the bottom outlet of a metallurgical vessel and incorporating a housing assembly according to the present invention
  • FIG. 2 is a transverse cross-sectional view of the arrangement of FIG. 1;
  • FIG. 3 is a top plan view of the cover member of FIG. 1 shown removed from the housing member but illustrating the novel joint constructions according to one embodiment of the present invention
  • FIG. 4 is an enlarged partial view of the lower right-hand portion of FIG. 1, but illustrating a modification of the joint configuration thereof;
  • FIGS. 5 and 6 are schematic views illustrating various manners of adjustment provided by the housing assembly of the present invention.
  • FIG. 1 there is shown schematically a bottom portion of a metallurgical vessel 10 including an outer metal jacket 10' interiorly of which is a refractory lining, not shown, through which extends a perforated nozzle brick 12 having therein a two-part refractory inlet sleeve or nozzle 13, 14 having therethrough a molten metal outlet orifice or opening 16.
  • a ring 11 supporting brick 12 Within jacket 10' is welded a ring 11 supporting brick 12, and within ring 11 is positioned a centering ring 15 to center brick 12 and inlet sleeve or nozzle 13, 14.
  • a sliding closure unit 20 includes a stationary housing assembly including a housing member 24 connected to ring 11 by attaching means 60, for example in the form of bolts 62, and also connecting to centering ring 15, for example by means of bolts 18 as shown in FIG. 2.
  • a stationary refractory plate 28 Within housing member 24 is supported a stationary refractory plate 28.
  • a cover member 26 is mounted on housing member 24 by means of joints to enable the cover member to be pivotable with respect to the housing member and to be removable therefrom.
  • Within cover member 26 is a movable frame 22 which supports a movable refractory plate 27 and which is movable in a rectilinear direction by means of a drive unit, only a rod 29 of which is shown in FIG. 1.
  • Plates 28 and 27 have complementary, abutting relative sliding surfaces, and frame 22 and plate 27 are pressed toward plate 28 in a sealing manner by means of springs assemblies in the form of spring 25 acting on pivotable levers 23.
  • the structure and manner of operation of such spring assemblies does not itself constitute a portion of the present invention, ut rather is the invention of a U.S. patent application entitled "APPARATUS FOR RELIEVING THE PRESSURE OF CLAMPING SPRINGS IN A SLIDING CLOSURE UNIT" filed on even date herewith by Hans Muller and Otto Kagi and assigned to the assignee of the present application. The disclosure of such application hereby is incorporated by reference.
  • cover member 26 When it becomes necessary to inspect or repair the internal components of the sliding closure unit 20, then cover member 26 must be pivoted with respect to housing member 24, or removed therefrom.
  • the cover member 26 is connected to housing member 24 in a manner to readily facilitate such opening pivotal movement or removal, and specifically to enable such operations to be achieved in a wide variety of directions, thereby to be accommodated to the particular available space adjacent the metallurgical vessel of a given installation.
  • the first and second sides have joint bases defining parallel first and second joint axes
  • the third and fourth oppositely spaced sides have joint bases defining parallel third and fourth axes.
  • the housing and cover members are generally of rectangular configuration having two long sides, i.e. the upper and lower sides in FIG. 3, and two short sides, i.e. the left and right sides in FIG. 3.
  • the first through third sides, i.e. the upper, lower and left sides in FIG. 3, of each of the housing and cover members having extending therefrom joint bases in the form of projections 36, 35, respectively.
  • the cover member may be pivotally mounted to the housing member to pivot about either of the long sides thereof, and in the arrangement shown in FIGS. 1-3 the cover member 26 is pivoted about the second side, i.e. the lower long side shown in FIG. 3 and the left side of FIG. 2.
  • the cover member 26 may alternatively be connected to the housing member 24 along the short sides thereof, rather than the long sides thereof. This is shown by dashed lines in FIGS. 1 and 3, wherein the third sides, i.e. the left sides in FIGS. 1 and 3, of the housing and cover members include joint bases in the form of projections 36, 35 identical to those of the long sides. Strap members may be connected in a pivotable manner between the projections 36, 35 of the short side in the same manner as discussed above. The opposite short sides of the housing member and cover member however are locked by a mechanism which is different from that discussed above regarding the long sides.
  • a lock joint 30' is defined by a latch member 32" pivotally mounted in joint bases formed along the respective side of cover member 26 and includes hook-shaped projections positionable over and latchable on corresponding projections formed inwardly of housing member 24.
  • This latching arrangement has the advantage that the locking joint substantially is housed within the housing assembly.
  • the lock joint 30' however can be replaced, as shown in FIG. 4, by a pair of locking joints 32 in the same manner as the locking joints 32 shown along the first side, i.e. the upper side of FIG. 3.
  • FIG. 5 and 6 illustrate different possible arrangements of mounting of the cover member 26 on the housing member 24 with respect to metallurgical vessels 40, 50. Specifically, FIG. 5 shows that the cover member may be mounted for lateral pivoting movement along either of the short sides, whereas FIG. 6 shows that the cover member may be mounted for lateral pivotal movement about either of the long sides. In both arrangements, the cover member 26 could be mounted for pivotal movement along the upper or lower sides.
  • FIGS. 5 and 6 illustrate an additional feature of the present invention.
  • connections 60 of the housing member 24 to the metallurgical vessel are shown as being at four equally circumferentially spaced position, i.e. at 90° intervals. Accordingly, the housing member itself may be rotated from the respective positions shown in FIGS. 5 and 6.
  • Connections 60 are shown as being located symmetrically around the axis of outlet 16. Rings 41 and 51 of FIGS. 5 and 6, respectively correspond to ring 11 of FIG. 1.
